The Company also announced that the FDA granted conditional approval for the brand name Phexxi™ (L-lactic acid, citric acid, potassium bitartrate) Vaginal Gel 1.8%/1%/0.4% on February 25, 2020. With this approval, the Company will now refer to its Multipurpose Vaginal pH Regulator (MVP-R™) candidate as Phexxi for the prevention of pregnancy and EVO100 for the prevention of chlamydia and gonorrhea.

"The Evofem team's exceptional execution in 2019 laid the groundwork for what will be a transformative year for the Company," said Saundra Pelletier, Chief Executive Officer, Evofem Biosciences. "We are rapidly approaching the established FDA PDUFA date for our innovative, hormone-free, investigational contraceptive gel, which we are thrilled to share is now branded as Phexxi.

"We remain focused on establishing a best-in-class sales force, initiating pre-commercial activities and continuing to disseminate compelling new data via conferences and publications. We are also preparing for other important catalysts that have the potential to drive future growth, including an end-of-phase 2 meeting with the FDA to discuss the potential path forward for EVO100 for the prevention of chlamydia and gonorrhea."

Fourth quarter and recent highlights include:

Resubmitted the NDA for Phexxi for the prevention of pregnancy and received a six-month review and Prescription Drug User Fee Act (PDUFA) goal date of May 25, 2020 from the FDA.

Reported positive, statistically significant top-line results from the Phase 2b AMPREVENCE study evaluating EVO100 for the prevention of chlamydia and gonorrhea in women. The study met its primary and secondary endpoints, demonstrating a 50% relative risk reduction in chlamydia infection and a 78% relative risk reduction in gonorrhea infection compared to placebo.

Three abstracts from the Phase 3 AMPOWER trial of Phexxi for prevention of pregnancy accepted for poster presentation at the American College of Obstetricians and Gynecologists' annual meeting.

Appointed Lisa Rarick, M.D., F.A.C.O.G., former FDA Division Director for the Division of Reproductive and Urologic Products, to the Company's Board of Directors.

Granted end-of-phase 2 meeting with the FDA to discuss AMPREVENCE study results and determine the clinical and regulatory path forward for EVO100.

Fourth Quarter Financial Results For the quarter ended December 31, 2019, total operating expenses decreased 14% to $12.9 million, compared to $15.0 million for the quarter ended December 31, 2018.

Research and development costs decreased $6.4 million, or 65%, to $3.4 million in the fourth quarter of 2019 versus $9.8 million in the prior year quarter. The decrease was primarily driven by lower clinical trial expenses reflecting completion of the clinical phase of the Phase 3 AMPOWER study in November 2018 and of the Phase 2b AMPREVENCE study in August 2019, offset by higher payroll related and consulting service fees.

General and administrative costs increased $4.2 million, or 81%, to $9.4 million in the fourth quarter of 2019 versus $5.2 million in the prior year quarter. This includes a $1.8 million increase in pre-commercialization sales and marketing related expenses, reflecting preparations for the potential approval and launch of Phexxi for the prevention of pregnancy in the second quarter of 2020; a $1.0 million increase in payroll related expenses due to increased headcount; a $1.0 million increase in consulting services; and a $0.1 million increase in noncash stock-based compensation in the fourth quarter of 2019.

As a result, net loss attributable to common stockholders improved to $12.7 million, or $(0.27) per share, for the fourth quarter of 2019 compared with a net loss of $15.0 million, or $(0.58) per share, for the prior year quarter.

Full Year Financial Results For the year ended December 31, 2019, total operating expenses decreased 32% to $52.7 million, compared to total operating expenses of $77.6 million for the year ended December 31, 2018.

Research and development costs decreased 49% to $22.2 million, compared to $43.4 million in the prior year period. The $21.2 million decrease in clinical trial costs during the year ended December 31, 2019 was primarily related to completion of the clinical phase of the AMPOWER and AMPREVENCE studies as previously noted.

General and administrative costs decreased 11% to $30.5 million, compared to $34.2 million in the prior year period. Noncash stock-based compensation decreased $7.2 million in the current period, since the majority of stock-based awards granted in 2018 vested that year. Professional services and personnel costs were $3.8 million lower due to the absence of one-time costs associated with the Company's January 2018 merger. These were offset by a $3.4 million increase in pre-commercialization advertising agency fees, public relations and sales support-related costs during the current period. Additionally, payroll related expenses and consulting services increased $2.3 million and $1.4 million, respectively, in the current period.

Total other expense was $27.3 million for the year ended December 31, 2019 and was primarily attributable to noncash charges related to the closing of our private placement during the second quarter of 2019, and to recognize various changes in the fair value of warrants of $4.4 million in the first quarter of 2019. Total other expense in the year ended December 31, 2018 was $48.1 million, and included noncash losses on the issuance of warrants and for the change in fair value of the Series D 2X liquidation preference.

As a result, net loss attributable to common stockholders improved to $80.0 million, or $(1.99) per share, for the year ended December 31, 2019, compared with a net loss of $125.8 million, or $(5.74) per share, for the year ended December 31, 2018.

Liquidity and Subsequent Material Events Unrestricted cash and short-term investments were $23.8 million at December 31, 2019, as compared to $35.8 million at September 30, 2019.

About Phexxi™ Phexxi (L-lactic acid, citric acid, potassium bitartrate) Vaginal Gel 1.8%/1%/0.4% is an investigational Multipurpose Vaginal pH Regulator (MVP-R™) designed to regulate vaginal pH within the normal range of 3.5 to 4.5, even in the presence of semen, which normally raises the vaginal pH to 7.0 to 8.0. This maintains an acidic environment that is inhospitable to sperm, as well as certain viral and bacterial pathogens associated with sexually transmitted infections, but is integral to the survival of healthy bacteria in the vagina.
